IMPROVEMENT IN SEnTTlNG UP SHIPS RIGGING.

Specification forming part of Letters Patent No. 29,204, datedV July 17,1860.

To all whom, it may concern:

Be it known that I, EPHRAIM U. THOMP- soN, of Bristol, in the county ofLincoln and State of Maine, have invented a certain new and usefulApparatus for Setting Up Ships Rigging; and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspeeltication.

My invention consists, first, in a device for grasping the ends of theshrouds, so that when the shrouds are set up every tiber bears itsproportionate share of the strain. At the ,same time the ends of theshrouds are sheathed and protected from the weather, thus preventingtheir decay.

Second, in a peculiar construction and coinbination of lanyard andjack,for'tlie purposes hereinafter explained.

In the accompanying drawings` Figure l represents a front elevationofthe lanyard and jack. or setting-up device. Fig. 2 is a side elevationof the same. Fig. 3 is a longitudinal section of the thimble, showingthe end of the shroud and lid partly in section.

A represents the shroud.

B is a thimble attached to the end of the shroud.

a is a f'errule fitting the end of the thimble.

C is a iid formed of' hard wood.

D is a cap fitting the end of the thimble.

F is a screw-bolt passing through the cap D into the end of the tid C.

b represents ears or lugs cast upon the periphery of the thinible B.

e are metal straps fitting over the ears b, and attached to theupper endof the lanyard E by an eyebolt, c. The straps are prevented fromspreading, and thereby slipping ott the ears, by a ring, d, fitting overtheir ends. The lanyard is formed of two pieces of metal, E E', ttingone within the other, of which the upper portion, E, is attached to theshroud and the lower portion, E', to the ship. The portion E is a solidbar of iron flaring downward on two sides. The portion E is formed ot'two elastic bars fitting over the portion E, as represented, and unitedbelow it in a solid bar, f, adapted to be fastened either to the chainor to replace the chain and be attached directly to the ships side.

g are loose collars which fit over the two parts of the lanyard, andserve the purpose of locking them together in any position in which theymay be set.

H is an iron bar constructed with a yoke, h, forming at its lower end anut with a lefthand thread.

I is a yoke attached at its lower end to the partf ot' the lanyard bymeans of a bolt, z',

and forming at its upper end a nut with a right-hand thread.

J is a right and left hand screw fitting the nuts in the yokes H and I,and rotated by a lever, L, so as to cause the said yokes to approach orrecede from each other, as desired.

K is a dog hooking over the top of the upper portion, E, of the lanyard,and attached to the bar H by any one of the holes li.

The operation is as follows: The thimble is first passed over the end ofthe rope. The latter is then opened and the lid inserted and the ropeend hawsed down onto it, being careful to keep the strands in properrelative position. NVhen fitted snug onto the ftd, worm and parcel andserve as in case of other fitting. A compress, M,ofthin sheet metal isthen y passed around, as seen in Fig. 3, its ends overlapping to permitits contraction upon the rope. Heave such turns as are needful in therigging by means of the projecting end of the tid, and haul down thethimble to the position shown 4in the drawings, drive the tid home. andsaw off the projecting end flush with the lower edge of the thimble.Next bore into the end ot' the iid and apply the cap D and screw F. Thendx the straps e to the thimble, as previously explained, attach the dogK and yoke I to the respective ends of the lanyard, rotate the screw Juntil the shroud is drawn thoroughly taut, and then drive down tocollars g, so as to hold the two portions of the lanyard firmly inposition. The jack H I J K may then be removed and the shroud willremain securely fixed.

I claim asnew and of my invention here- 11il. rIhe combination of thefid C and thimble B, constructed, applied, and operating substantiallyas and for the purposes set forth.

2. The lanyard E E', constructed and operating substantially asdescribed.

3. The described combination of the jack H I J K and lanyard E E',operating as set forth.

In testimony of which invention I hereunto set my hand.
